Reactive Functional Programming made simple. You may have or may have not used RxJs and experimented or developed apps with Subjects, Observables and transformation of observables through piping RxJs operators. In this 30 minute presentation we will make things simple. We will go through examples of what they are and how they are made, as well as what problems they solve. We will also see how to build our own RxJs operators that implement synchronous and asynchronous data flow patterns.
